Specification of Letters Patent.

lpplication filed August 27, 1919. Serial No. 320,185.

and State of North Carolina, have invented a new and useful Closet-Valve, of which the following is a specification.

The device forming-the subject matter of this application is a siphon for a flush tank, and the invention aims to provide novel means for starting the action of the siphon.

It is within the province of the disclosure to improve generally and to enhance the utilitylof devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention. I

In the accompanying drawings Figure 1 shows in vertical section, a portion of a flush tank embodying the improvements hereinafter claimed; Fig. 2 is a top plan of the valve disk; Fig. 3 is an elevation of the valve disk; Fig. 4 is a plan of the head wherewith the valve disk coacts; Fig. 5 is an elevation of the head Fig. 6 is a top I plan showing a portion of a flush tank wherein the device forming the subject matter of this application has been embodied; and Fig. 7 is a cross section taken approximately on the line 7--7 of Fig. l. v

The numeral 1 denotes a flush tank to which water is supplied through apipe 2.

As is common in devices of this kind, the flow of the water through the pipe 2 is controlled by a float-actuated valve, but since the float-actuated valve is a common and well known construction, it is alluded to briefly, without specific delineation in the drawlngs.

The numeral 3 denotes, generally, a

' siphon, including an outlet leg 4 and an inlet leg 5, the leg 5 terminating at its lower end in a cylindrical enlargement 6, spaced from the bottom of the tank 1. The outlet leg 4 is secured in any desired way as shown at 7, to the bottom of the tank 1.

The inlet leg 5 carries a guide 8, and there is an opening 9 in the top of the enlargement 6, a cup 10 being formed about the opening 9, the cup preferably being integral wlth the top of the enlargement 6 and the inlet leg 5. Internally, the enlargement is supplied with stops 11.

A plunger 12 is mounted. to reciprocate in the guide 8 and in the opening 9, the plunger being operated from a convenient point by any suitable means (not shown). The lower end of the plunger 12 is secured at 14 to the hub 15 of a head 16 having a close sliding fit in the enlargement 6, the head 16 preferably being in the form of a spider. The numeral 17 denotes a valve, in the form of a disk, adapted to rest on the head 6 and servlng as a closure for the openings in the head, the valve having a neck 18 receiving the plunger 12, the valve 17 thus being mounted to slide on the plunger.

lVhen the plunger 12 is raised, the head 16 will be raised, along with the valve 17. \Vater in the enlargement 6 and in the inlet leg 5 will be lifted and will pass over into the outlet leg 4. theflow through the siphon being started in this way. The stops 11 limit the upward movement of the head 16 so that the head 16 cannot move upwardly,

Vhen the flow through the siphon 3 has been started as above described, the water in the tank 1 passes upwardly through the enlargement 6 and theinlct leg 5, the water flowing downwardly through the outlet leg 4, until the tank is empty. As the water flows through the siphon 3 in the way above described, the valve 17 rises,"responsive to the flowing water, and permits the water to pass through the siphon, the valve clearing the stops 6. \Vhcn the plunger 12 is released, the same moves downwardly, along with the head 16, and when the water has flowed through the siphon 3, until the siphon sucks air through the lower end of.

the enlargement 6, the valve 17 moves down wardly on the plunger 12 and seats on the head 16, under the weight of the water in the inlet leg 5. The cup 10 is normally filled with water and prevents the entrance of air Y inlet leg receiving the contents of the tank,

the inlet leg comprising a lower enlarge-- ment and an upper reduced portion, the enlargement having an opening in its top; a cup formed inte rally with. the enlargement and the reduce juncture therebetween, and extended around the opening, the cup constituting a water seal for the opening and constituting a re 'inforcement uniting the enlargement and the reduced portion of the inlet leg; a plunportion, at the point ofger slidable in the opening; a head secured to the plunger and fitting slidably in the enlargement, the head having an opening; and a valve sliclable on the plunger, the valve controlling the opening in the head.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
